Ignatius, Hermas, Irenaeus, Justin Martyr, Tertullian, Origen, and Lactantius all speak this way. Many of these writings also connect demons with false worship, spiritual danger, and exorcism in Jesus’ name.

What did early Christians believe about evil Spirits and Demonic Powers?
Early Christian writings teach that evil spirits and demons were real hostile powers, not just symbols for bad habits. Writers like Ignatius, Hermas, Irenaeus, Justin Martyr, Tertullian, Origen, and Lactantius say these spirits attacked people, spread error, and were driven out by Christ’s authority and the name of Jesus. The witness is broad across the 1st to 3rd centuries, and it is especially strong on exorcism, spiritual warfare, and the defeat of demons through Christ.
Some writers also link demons with pagan worship and false gods, while a few later or less direct passages speak more generally about “powers” and “principalities.” Many more early Christian quotations, Bible passages, and source links are gathered below so you can study the evidence for yourself.

Questions Answered by the Sources

Irenaeus, Against Heresies: Book II Direct teaching

Tertullian, Apology Direct teaching
...them at least remove from themselves the mark of disgrace and condemnation. They deny that they are unclean spirits. Yet we must hold this to be proved beyond doubt by their delight in blood and fumes and the foul carcasses of sacrificial animals, and even by the vile language of their ministers. Let them deny that, already condemned for their wickedness, they are kept for that very day of judgment, together with all their worshipers and their works. Why, all the authority and power we have over them comes from naming the name of Christ and calling back to their memory the woes with which God threatens them at the hands of Christ as Judge, and which they expect will one day overtake them. Fearing Christ in God, and God in Christ, they become subject to the servants of God and Christ. So at our touch and breathing, overwhelmed by the thought and realization of those fires of judgment, they leave the bodies they have entered, unwilling and distressed, and before your very eyes they are put openly to shame. You believe them when they lie. Then believe them when they speak the truth about themselves. No one lies to bring disgrace on his own head, but rather for the sake of honor. Yo

Origen, Against Celsus Direct teaching
And it is not only we who speak of wicked demons, but almost everyone who admits that demons exist. So then, it is not true that all keep the law of the Most High. For all who turn away from the divine law, whether through carelessness, or through corruption and vice, or through ignorance of what is right, do not keep the law of God. Instead, to use a new phrase that we find in Scripture, they keep the law of sin. I say, then, that in the opinion of most people who believe that demons exist, some of them are wicked. These, instead of keeping the law of God, sin against it. But according to our belief, this is true of all demons: they were not demons at first, but became so by departing from the true way. So the name demons is given to those beings who have fallen away from God. Therefore, those who worship God must not serve demons. We can also learn the true nature of demons if we consider what those do who call on them by charms, either to prevent certain things or for many other purposes. For this is the method they use: by incantations and magical arts they call on demons and lead them to help carry out their wishes. Therefore, the worship of all demons would be inconsistent fo

And after they have gone out, let him say: You energumens, afflicted with unclean spirits, pray, and let us all earnestly pray for them, that God, who loves mankind, will by Christ rebuke the unclean and wicked spirits, and deliver His supplicants from the dominion of the adversary. May He who rebuked the legion of demons, and the devil, the prince of wickedness, Mark 5:9; Zechariah 3:2, even now rebuke these apostates from piety, and deliver His own workmanship from his power, and cleanse those creatures whom He has made with great wisdom. Let us still pray earnestly for them. Save them, O God, and raise them up by Your power. Bow down your heads, you energumens, and receive the blessings. And let the bishop add this prayer, and say:

Lactantius, The Epitome of the Divine Institutes Direct teaching
...t demons to confusion by His word and command, so now, by the name and sign of that same suffering, unclean spirits that have slipped into the bodies of men are driven out. While they are racked and tormented, and while they confess that they are demons, they give way to God, who afflicts them. Therefore, what can the Greeks expect from their superstitions and from their wisdom, when they see that their gods, whom they also do not deny to be demons, are overcome by men through the cross?
-
Lactantius, The Epitome of the Divine Institutes Direct teaching
And as He Himself before His passion put to confusion demons by His word and command, so now, by the name and sign of the same passion, unclean spirits, having insinuated themselves into the bodies of men, are driven out, when racked and tormented, and confessing themselves to be demons, they yield themselves to God, who harasses them.

Did early Christians believe believers wrestled with spiritual powers?
A repeated theme is that Christians struggle against principalities, powers, rulers of darkness, and spiritual wickedness. The sources present this as a real spiritual conflict, not just a metaphor for ordinary human problems.

Ignatius, The Epistle of Ignatius to the Ephesians (Long Version) Direct teaching

-
Ignatius of Antioch, Connection to Ephesians 6:12 Direct teaching
Nothing is better than that peace which is according to Christ, by which all war, both of aërial and terrestrial spirits, is brought to an end. "For we wrestle not against blood and flesh, but against principalities and powers, and against the rulers of the darkness of this world, against spiritual wickedness in heavenly places."
-
Origen, De Principiis (On First Principles) Direct teaching
...ration indeed in the Epistle to the Ephesians, "We wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places," must be understood as if we meant, "I, Paul, and you Ephesians, and all who have not to wrestle against flesh and blood." For such have to struggle against principalities and powers, against the rulers of the darkness of this world, not like the Corinthians, whose struggle was as yet against flesh and blood, and who had been overtaken by no temptation but such as is common to man.

Origen, De Principiis (On First Principles) Direct teaching

Tertullian, Against Marcion Supporting witness
...t be two, I intend to follow Him who first taught the lesson. But since our struggle is against the rulers of this world, Ephesians 6:12, how many Creator Gods there would have to be! For why should I not insist here that he should have mentioned only one ruler of this world, if he meant that only the Creator was the being to whom all the powers already mentioned belonged? Again, in the previous verse he tells us to put on the whole armor of God, so that we may be able to stand against the wiles of the devil, Ephesians 6:11. Does he not show that all the things he names after the devil really belong to the devil: the principalities and the powers and the rulers of the darkness of this world, Ephesians 6:12? We also assign these to the devil's authority. Otherwise, if the devil means the Creator, who then will be the devil in the Creator's divine arrangement? Since there are two gods, must there also be two devils, and many powers and rulers of this world? But how can the Creator be both devil and God at the same time, when the devil is not at once both god and devil? For either both are gods, if both are devils, or else He who is God is not also devil, just as he who is the devi
Did early Christians connect demons with pagan gods and idols?
Several authors say the gods of the nations were really demons or unclean spirits, and that idolatry involved fellowship with devils. They also portray demons as active in pagan shrines, oracles, and false worship.
-
Justin Martyr, The First Apology Direct teaching
Thirdly, after Christ's ascension into heaven, the devils influenced certain men who claimed to be gods. Not only were they not persecuted by you, but they were even honored. There was a Samaritan named Simon, from a village called Gitto, who, during the reign of Claudius Caesar, performed mighty acts of magic in your royal city of Rome, through the influence of devils working in him. He was regarded as a god and honored by you with a statue, which was erected on the River Tiber between the two bridges, bearing this inscription in the Roman language: "Simoni Deo Sancto," meaning "To Simon the holy God." Almost all the Samaritans and even a few people from other nations worship him and acknowledge him as the first god. A woman named Helena, who traveled with him at that time and was formerly a prostitute, is said to be the first idea generated by him. A man named Menander, also a Samaritan from the town of Capparetæa and a disciple of Simon, was inspired by devils and is known to have deceived many in Antioch with his magical arts. He convinced his followers that they would never die, and even now some people still hold his beliefs. Marcion, a man from Pontus, is alive today and tea

Clement of Alexandria, Exhortation to the Heathen Direct teaching
How, then, can shades and demons be still reckoned gods, being in reality unclean and impure spirits, acknowledged by all to be of an earthly and watery nature, sinking downwards by their own weight, and flitting about graves and tombs, about which they appear dimly, being but shadowy phantasms?

Minucius Felix, Octavius Direct teaching
Therefore, these impure spirits—the demons—as is shown by the Magi, by the philosophers, and by Plato, consecrated under statues and images, lurk there. By their afflatus they gain the authority of a deity that seems present. Meanwhile, they are breathed into the prophets. They dwell in shrines. Sometimes they animate the fibers of the entrails, control the flights of birds, direct the lots, and cause oracles tangled with many falsehoods. For they are both deceived, and they deceive, since they are ignorant of the simple truth, and for their own ruin do not confess what they know. Thus they weigh men down from heaven and call them away from the true God to material things. They disturb life and make all men unquiet. They also creep secretly into human bodies. With subtlety, because they are spirits, they feign diseases, alarm minds, and wrench limbs, so that they may force men to worship them. Then, after being glutted with the fumes of altars and the sacrifices of cattle, by loosening what they had bound they seem to have cured it. These raging maniacs also, whom you see rushing about in public, are themselves prophets without a temple. Thus they rage, thus they rave, thus they ar

Lactantius, The Divine Institutes Direct teaching
...other times as gods. Of these names, one is true and the other is false. For when those most wicked spirits are put under oath, they then confess that they are demons. But when they are worshiped, they falsely say that they are gods, so that they may lead people into error and draw them away from the knowledge of the true God, by which alone eternal death can be escaped. These are the same spirits who, to overthrow man, established various forms of worship for themselves in different regions, though under false and assumed names, so that they might deceive. Because they were not able by themselves to rise to divinity, they took for themselves the names of powerful kings. Under those titles they claimed divine honors for themselves. But this error can be driven away and brought into the light of truth. For if anyone wants to examine the matter further, let him gather those who are skilled in calling up spirits from the dead. Let them call up Jupiter, Neptune, Vulcan, Mercury, Apollo, and Saturnus, the father of all. All will answer from the lower regions, and when they are questioned, they will speak and make confession about themselves and about God. After this, let them call up
